Detection operation (2)
The only blemish address which is held is the highest-level blemish address within a frame, when the
conditions of detection operation (1) are satisfied, and the target pixel is at or above a level consisting of the
threshold level set in the parameter DETREFL/M plus the pixel level of each of two pixels of the same color
filter which are adjacent in the horizontal direction.

Detection operation (3)
If a blemish address held in detection operation (2) matches the address from N fields earlier, then a blemish is
recognized. The number of fields N can be set using the parameter FLDWAIT.
Compensation operation
Blemish pixels are corrected by replacing them with the average value of two pixels of the same color filter
which are adjacent in the horizontal direction (same as for static detection and compensation).
* The results of blemish detection and compensation appear in “Table 11.2-15 Parameters for storing blemish
detection results”.
